Keith John Moon (23 August 1946 - 7 September 1978) was an English musician who was the drummer for the rock band the Who. Regarded as one of the greatest drummers in the history of rock music, he was noted for his unique style of playing and his eccentric, self-destructive behaviour.

Moon grew up in Wembley and took up the drums during the early 1960s. After playing with a local band, the Beachcombers, he joined the Who in 1964 before they recorded their first single.
